Abstract

The purpose of this study is to study the technical implementation methods to prevent problems such as the record of important educational activities of the student life record department or the continuous illegal leakage and manipulation. To this end, in this paper, by applying a private blockchain that can be participated only by a given organization or individual, it prevents outsiders from participating in the block network, and creates legitimate authority by creating two types of block data: student information block and access record block in the life record book. We proposed a block mechanism that can be registered, modified, and accessed only by authorized staff members. As a result, we have prepared an alternative to prevent forgery and alteration of the living records by third parties and to secure the integrity of the living records. If applied to the educational administrative information system, social consensus will be established that the operation and management of the life record book is reliable.

본 연구의 목적은 시·도교육청 교육행정정보시스템 학생생활기록부가 중요한 교육활동의 기록이나, 지속적으로 불법유출·조작하는 등의 문제점을 방지하기 위한 기술적 구현방법을 연구하는 것이다. 이를 위해 본 논문에서는 정해진 조직 또는 개인만이 참여할 수 있는 프라이빗 블록체인을 적용함으로서 외부자에 의한 블록네트워크 참여를 방지하고, 생활기록부 학생정보 블록과 접근기록 블록 두 종류의 블록 데이터를 생성하여 정당한 권한을 부여받은 실무자에 의해 서만 등록, 수정, 접근할 수 있는 블록 메커니즘을 제시하였다. 그 결과, 제3자에 의한 생활기록부의 위·변조방지와 생활 기록부의 무결성 확보를 할 수 있는 하나의 대안을 마련하였으며, 실제 교육행정정보시스템에 적용하게 된다면 생활기록부 운영과 관리가 신뢰할 수 있다는 사회적 공감대를 확보하게 될 것이다.
